최근 전기자동차를 포함하여 2차전지의 응용가치가 급격하게 증가하고 있으나 액체 전해질을 사용함에 따라 안전성 강화가 커다란 이슈가 되고 있다. 이를 위해 MOF, COF 등의 결정성 다공성 물질을 이용하여 양성자의 통로로서 이용하고자 하는 노력이 있다. 본 논문을 통해 이러한 기술의 발전에 대한 이해를 돕고자 한다.
Crystalline porous materials are currently a hot research topic in the field of proton-conducting materials. Crystalline porous materials include metal？organic frameworks (MOFs), coordination polymers (CPs), polyoxometalates (POMs) and covalent organic frameworks (COFs). The designable structures and high surface areas of these materials provide great opportunities to orderly accommodate proton carriers and to systemically modify the concentration and mobility of proton carriers in available spaces. Based on the understanding of the relationship between the structure and proton conductivity, controllable synthesis of porous materials with high proton conductivity will gradually be achieved. This review summarizes the emerging studies of these materials and their unique proton conductivities.
